I am sure Albert Silver (who wrote the article) is very proud he wrote the strongest engine in the world.

Re: Anyone heared of MuZero ?

>Assuming the "steps" they refer to are games

It's training steps of 2048 minibatches. I don't see any mention of games - they run the processes asynchronously. But it seems they generated about 20 billion positions. So, probably quite a bit more than a million games.

This shows Fat Fritz being 40-50 Elo weaker? Rather incompatible results, unless 49921 is a very weak net or something.

Re: UCI Win/Draw/Loss reporting

You can use the logit of the probability of winning, and multiply it by a constant so that it looks like centipawns. I do this for my program, and it works very well. I use this, which is the same thing right? https://www.chessprogramming.org/Pawn_Advantage,_Win_Percentage,_and_Elo It's convenient ...

Re: UCI Win/Draw/Loss reporting

I missed this discussion. So what is agreed up on: info wdl 200 600 200 format for uci, and what for xboard? Thanks. I don't think anything has been agreed upon, but Fritz 17 is now confirmed to ship with a modified lc0 that has the patch pointed out in the original post: https://github.com/DanielU...

Re: Some words on Leela Go Zero

GPU: RTX 2070 May network versus elfv2: 10:10 October network versus elfv2: 12:8 So, the "700 Elo points" in self ratings is hugely inflated, and the progress is probably no more than 100 Elo points in 5 months, quite modest for Go. It's hard to say anything from such a short match, no? I think the...

Re: UCI Win/Draw/Loss reporting

Well, what is most wrong about 'wdl' as proposed is that it is partly redundant: the three values must sum up to 100. It would be more elegant to have the expected score (winprob + drawprob/2) as a new score mode (as alternative to 'mate' and 'cp'), and add a new info 'drawprob' with a single value...

Re: UCI Win/Draw/Loss reporting

I may add, uci protocol encourages clear key names, example, info depth, the word depth is fully spelled out. info score, the word score is fully spelled out too. info multipv and others. wdl is not clear, is it probability? is it a counter of something? winprob is more clearer to denote win probab...

Let me suggest a description about self-explaining data in which engines can tell chess GUIs how to display their data in the form of tables.
There is zero chance I'd be willing to shift the decision on how to present data from the USER INTERFACE to the ENGINE.
